Fractal zoom video calculated in
KF (515 keyframes forming an exponential map) in 66mins wall clock time, then assembled and encoded into a 3min video in 12mins wall clock time.
I implemented the
video assembler in C++ using OpenGL GLSL shaders to colour the raw iteration data, modified from an earlier flat keyframe interpolator to work with exponential map slices.
The colouring is based on directional distance estimate - close to the fractal is black, with rainbow fringes surrounding desaturating to white far from the fractal.
